ViaMichelin maps site

Hi, since Europe maps are not yet implemented by Yahoo and Google, the only site where to get navigation aids like maps and itinerary is www.viamichelin.it (.de, .fr, etc.). Using my brand new Treo650 (IBM Java installed, and standard Blazer Web Browser), I can see the map (best in expanded view), and the cursor which is used to set the zoom scale. Unfortunately if I press the cursor, nothing happens. Is there anything I am missing or that I can do in order to have the site working properly?? Or, is there any web browser that works properly with this site??
Many thanks in advance
Giovanni
